#D "catacryst", a 58-cell quadratic growth pattern
#D Nick Gotts, 21 Apr 2000
#D
#D This was at one time the smallest known pattern with a
#D faster-than-linear growth rate. It has since been surpassed
#D by the related "metacatacryst".
#D
#D The catacryst consists of three arks plus a glider-producing
#D switch engine. It produces a block-laying switch engine every
#D 47616 generations. Each block-laying switch engine has only
#D a finite life, but the length of this life increases linearly
#D with each new switch engine, so that the pattern overall
#D grows quadratically, as an unusual type of MMS breeder.
#D
#D This is a quite sparse pattern, so the View->Find Active Cells
#D command may come in handy.
